Overview
Designed to accelerate mission-critical
application performance, VersaCache is the largest, fastest external caching
appliance in existence. While CPU processing power has doubled every 18 months,
disk drive performance, as measured by mechanical and rotational latency, has
only doubled once in the last 10 years. The performance gap between computers
and external disk storage continues to widen. As a result, applications and
users spend much of their time waiting for the retrieval of data from disk,
lowering productivity and wasting CPU cycles. VersaCache is designed to
alleviate the performance bottleneck omnipresent in today’s Fibre Channel
storage networks by using high speed DDR memory to provide up to 128 gigabytes
of near-zero latency storage per 5U subsystem.
VersaCache Flexibility
VersaCache can be directly attached to a server
or can be deployed in a Fibre Channel storage area network (SAN) environment
where multiple servers can share the system’s caching resources. The
system supports all Fibre Channel topologies and connection speeds up to
4Gb/s.
VersaCache is the industry’s only caching appliance that
can be partitioned as a block-level SAN cache and as a file cache (i.e. solid
state disk). The subsystem can be used as all SAN cache, all solid state disk
(SSD), or as a combination of both. This flexibility allows VersaCache to be
configured and tuned to provide optimal performance for a given customer’s
application environment. By supporting both caching methods in a single
subsystem, customer’s can achieve the best possible
price/performance.
Since VersaCache is designed with an industry
standard disk interface, applications will run without modification protecting
the customer’s investment in application software.
The
system’s modular architecture supports field upgrades of memory capacity
(in 16GB increments) and Fibre Channel links to easily scale both system
capacity and performance.
